COLD-PROOF SERVICE-TRAY.

Specicaton of Letters Patent.

Patented Jan. 12, 1915.

Application led May 6, 1914. Serial No. 836,688.

To all whom it may concern.'

Be it known that I, EDWARD L. STINE, a citizen of the United States, resident of Buffalo, in the county of Erie and State of New York, have made a certain new and useful Invention in Cold-Proof Service-Trays; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l is a perspective view of the invention with the cover partly removed. Fig. 2 is a central vertical longitudinal section of the invention on the line 2 2, Fig. 3. Fig. 3 is a plan view of the lower or bottom tray.

'Ihe object of the invention is to provide means to facilitate the service of hot meals in hotels and elsewhere, and it consists in the novel construction and combination of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 2, indicates a double wall tray in which the dishes containing the hot articles of food are designed to be placed, and 3, a second tray of substantially similar form and size, which is designed to be inverted over the bottom tray to cover in the dishes and articles contained thereby.

Each of these trays is made with double walls, as indicated at 4, 4, the bottom portion being strengthened and supported by bracing between the walls, said braces indicated at 5, extending longitudinally and transversely of the trays. Between the linings a light filling 6, of cork or other suitable nonconducting material, is usually employed. An interior flange 7, projecting from the margin of one of these trays, is designed to engage the marginal portion of the other tray where the two are closed together, and serves to hold the trays in relative position. The upright wall of `each tray is several inches high, being made about half the height of a coee pot or other tall dish, so that when the two trays are put together such. a vessel or dish will be entirely closed in, and yet when the trays are separated, shallow dishes can be easily reached for conveyance to the table. It is necessary, on account of the weight, to provide yeach tray with strong handles 8, these being usually made vof wood and secured to the ends of the trays by brackets 9.

When the trays are separated the covering tray can be used for holding dishes to be taken from the table, or for such disposition of the dishes in the bottom tray as may be advisable before placing them on the table. As these trays are necessarily of large size, aluminum is preferred as the material from which they are made, it being light and having the requisite rigidity. When closed together this carrying device is not designed to be air-tight, as such a construction would not be conducive to the best condition of the articles of food.

This device is designed to supply a practical and convenient vehicle for the purposes involved, and while I am aware that it is not new to make double wall refrigerators and cookers of various kinds, as well as double pans for baking, these articles are foreign to my invention.

It is preferred that the end handles of each of the trays shall be located midway of the height of the tray, so that when the cover tray is reversed to carry dishes, the handles will have the same relation thereto as the end handles of the bottom tray have relation thereto. It is also preferred that the flange extension 7 shall be made integrally of the inner wall of the cover tray and doubled as shown so that it may be economically manufactured and strong and durable.

The longitudinally and transversely extendingbraces between the inner and outer bottom wallsof the bottom tray will prevent sagging of the inner of the bottom walls when the carrier is loaded with the filled dishes, and the space between said braces need not be filled in with the non-conducting material as the air therein included will be a sufficient non-conductor.

What I claim is:

A carrier for dishes, comprising a bottom tray having a bottom and upright sides consisting of inner and outer walls having a nonconducting filling between the walls, the inner and outer bottom walls having a central longitudinally and transversely extending brace located between the same, and a similar inverted Cover tray having a bottom In testimony whereof affix my signature, and upright sides consisting of inner and 1n presence of two witnesses. outer walls havmg also a non-conducting filling between the walls, the inner walls EDWARD L STINE' 5 having an integral doubled flange extension Witnesses:
